SPECIFICATION formingpart of Letters Patent No. 735,573, dated August 4, 1903.

Application filed December 9, 1902. Serial No. 134,500. (No model.)

T0 on whom, it may concern:

Be it known that I, ANTON OLEsZKIEWIcZ, a subject of the Emperor of Russia, and a resident of Bielaia-Zerkov, Russia, (whose post-office'address is Bielaia-Zerkov, government of Kiev, Russia,) have invented certain new and useful Improvements in Cycles, of which the following is a specification.

This invention relates to an improved means for accelerating the speed of cycles, and has for its object to provide means to be operated by the body of the operator to add to the speed attained through the pedal power. It is particularly applicable to a cycle fitte with a coaster-brake or free wheel.

In the accompanying drawings, Figure 1 is a side elevation of a bicycle fitted with my improved driving means. Fig. 2 is a perspective view of a girdle to be used therewith. Fig. 3 shows the operating-lever in side and plan view. Fig. i is an enlarged view of the rear portion of the cycle broken away. Fig. 5 shows a detail of the free-wheel mechanism in side and edge view. Fig. 6 shows the pivoted barrel to be placed between the forks, and Fig. 7 shows the pulley Z.

The diskA of the free-wheel mechanism is provided with an extending arm pivotally connected to a rod 0, the other end of which is pivotally connected to an arm 0 of a threearmed barrel F, Fig. 6, free to turn in bearings in the rear forks of the frame. An arm 6 of the barrel provided with an antifriotionroller 1' extends forwardly, while an arm it extends rearwardly and has connected to its outer end a rod 12 which in turn is connected to a strong spring 13, secured at Q to the frame.

A lever '1, Figs. 1 and 3, pivoted to the frame at q, is provided at its rear end with a pawl O, which is pivoted at r and is maintained normally by a spring 7a, with its rear end against a pin f, Fig. 3. The pawl can be turned on its pivot to throw its right-hand end upward, Fig. 1, against the pressure of the spring 710.

To the outer end of the lever T at a is connected a cord H, which passes over a pulley Z on the frame and is connected to the girdle P bya hook s, or when not in use to a hook N, beneath the saddle, Fig. 1. A spiral spring M,secured to the upper bar of the frame and to the lever T, always tends to keep the lever in the position shown in Fig. 1.

In operation the rider places the girdle over his shoulders, and should he care to accelerate his speed over that obtained by pedaling he will attach the outer end of cord H to his girdle P. By straightening up in his saddle the cord II will pull downward the lever T and cause the pawl O to act on the arm e of the barrel F, and, so moving the rod 0 in the direction of the arrow 71, pulling down on the rod y and tensioning the spring B. Should the pawl 0 now pass the roller 1; or should the rider release the pull on the cord H, the spring 13 will powerfully return the 'barrel F and will draw the rod 0 in the direction of the arrow a so as to turn the disk A and add the tension of the spring B to the rotative power already acting on the free wheel from the action of the riders feet at the pedals.

I claim as my invention 1. Acycle having a free-wheel mechanism, a spring adapted to be tensioned by the rider and means connecting the tensioned spring operatively to the free wheel mechanism, whereby, on the release of the spring by the rider, the tension thereof will operate to accelerate the speed of the cycle, substantially as described.

2. Acycle having a free-wheel mechanism, a rod operatively connected to and adapted to operate said free-wheel mechanism,aspring connected to said rod and means to be operated by the rider to tension said spring and then to release it to permit the spring to act to accelerate the speed, substantially as described.

3. A cycle having a free-wheel mechanism, a barrel, a spring, an operating-lever, a 'pawl at one end thereof and a cord secured at the other, three arms to the barrel, one in the path of travel of said pawl, one connected to said spring and one to said free-wheel mechanism, substantially as described.

In witness whereof I have hereunto set my hand in presence of two witnesses.
